I've had greylist up and running now for about a month, and nothing gets blacklisted, and it hasn't cut down on any spam. Here's the config file: ######################################################################## ### FILE: /etc/greylistd/config ### PURPOSE: Configuration settings for the "greylistd(8)" daemon ######################################################################## [timeouts] # Initial delay before previously unknown triplets are allowed to pass # Default is 10 minutes = 600 seconds retryMin = 3600 # Lifetime of triplets that have not been retried after initial delay # Default is 8 hours = 28800 seconds retryMax = 28800 # Lifetime of auto-whitelisted triplets that have allowed mail to pass # Default is 60 days = 5,184,000 seconds expire = 5184000 [socket] # Path to the UNIX domain socket on which greylistd will listen. # The parent directory must be writable by the user running 'greylistd'. # Default path is "/var/run/greylistd/socket". path = /var/run/greylistd/socket # UNIX filemode of that socket. See "chmod(1)" for the meaning of this. # Default mode is 0660. mode = 0660 [data] # Update interval -- save data to the filesystem if if has been more # than this many seconds (default 600) since the last save. update = 600 # Path to the file containing the current state of each data item (triplet), # along with some general statistics. # Default is "/var/lib/greylistd/states". statefile = /var/lib/greylistd/states # Path to the file that will contain the original, unhashed data for the # "list" command. Default is "/var/lib/greylistd/triplets". tripletfile = /var/lib/greylistd/triplets # Whether or not to retain unhashed triplets, for the "list" command. # Default is "true" savetriplets = true # Whether check/update also checks for an whitelist entry, which only # contains the first word of the triplet, that is the IP address usually. # If set to true, you can also insert general IP addresses/networks into the # whitelist, without email addresses. singlecheck = false # Whether update only inserts the first word of the triplet into the # whitelist, that is the IP address usually. Meant to be used in # conjunction with singlecheck = true. singleupdate = false ########## End greylist config ####################### I even emailed the author (since he published his email address and invited users with question to do so), but, of course, got no reply. I haven't seen this in any forums, and am wondering if anyone is using it. TIA, -- anw --
